Glycerol Definition• A syrupy, sweet, colorless or yellowish liquid,
obtained from fats and oils as a byproduct of saponification and used as a solvent, an antifreeze, a plasticizer, and a sweetener and in the manufacture of dynamite, cosmetics, liquid soaps, inks, and lubricants.
• Glycerol residues are obtained from production of palm oil kernel through glycerol refining.

Neutralization Process• Mixing of sodium hydroxide (using
dosing pump) and heating at 90 ° Celsius to neutralize the solvent.
• Analogue inputs: temperature sensor, pH sensor
• Discrete inputs: Liquid level switches
• Analogue inputs connected to DeviceNet
• Discrete input/output connected to CQM1-H unit
